Abstract

PURPOSE: A device for locking a computer keyboard/mouse by a wireless approaching device is provided to prevent operation of the mouse and the keyboard if a user is escaped from a computer over a predetermined distance by making the user hold a portable wireless transmitter and attaching a wireless receiver to the computer. CONSTITUTION: The portable wireless transmitter informs the computer(4) that the user is close to the computer by transmitting an ID code of the user periodically. The ID code transmitted from the portable wireless transmitter is received to the wireless receiver(1) and is sent to a computer controlling program(3). If the received ID code is identical with the ID code stored in the computer controlling program, the user uses the computer. If the ID coed is not received for a predetermined time, the computer controlling program determines that the user is present in a place not using the computer and automatically operates a locking device for the keyboard and the mouse.

Description

Wireless approach device for locking computer keyboard and mouse {Wireless approach installation for computer keyboard and mouse lock system}

The portable wireless transmitter 2 transmits the ID code wirelessly, and at this time, the wireless receiver 2 receives the ID code. The portable radio transmitter 2 is designed to be carried by a person, and when the portable radio transmitter is out of a certain distance, the corresponding ID code is not received. In this case, the device locks the computer's keyboard and mouse. In order to prevent mouse and keyboard operation, it is a device that sends a message to KERNEL of OS so as not to intercept or operate keyboard and mouse messages from KERNEL of computer OS.

There is a need to limit the amount of time a child or teenager spends too much time playing games, chatting, etc. In addition, if necessary, sites that are considered harmful to pornography sites, violent game sites, and so on, are desperately needed in the current society. However, if there is no appropriate countermeasure and simply relying on software, such a restriction can be easily used by adolescents to terminate the content of access control programs. In the present invention, an ID code is received from a portable wireless transmitter, which is a locking device and a key device, and a hardware device is added to a device that relies only on nonsense software. In this case, it is possible to set the usage time and access blocking site so that the youth cannot operate it without the portable radio transmitter.

The ID code, which is an identification code of the transmitter, is transmitted by using the communication distance of the low power wireless transmitter to receive the ID code of the transmitter from the receiver. At this time, if the portable small power transmitter is out of a certain distance from the receiver attached to the computer, the receiver does not receive the ID code, which is the identification code of the transmitter. At this time, it is a device for preventing other people from operating the mouse and keyboard to prevent their computer operation. In a computer program, an ID code signal received from a wireless receiver is processed by a computer control program. This processing method is the control program technology that prevents keyboard and mouse operation from the KERNEL of the computer OS and the ID code received from the wireless receiving device (1). The USB PORT, PRINT PORT, SERIAL PORT, INTERFACE Program it so that it can be delivered anywhere in the CARD. In addition, the ID code can be managed by the group. For example, in the case of a small and medium-sized company, the portable cordless transmitter ID code of the CEO or computer system manager can be configured to operate the entire computer of the company. Only computers that are subordinate to the team can be operated, and the general practitioner can manage the group so that only his computer can operate. In the case of a computer control program, the control program should also be run when the computer OS boots. Therefore, the ID code of the portable radio transmitter cannot be operated unless the ID code authorized by the wireless receiver attached to the computer is received.

In order to reduce the amount of time spent playing games, chatting, etc. with the computer for the proper use of the computer, a device that allows the user to use the computer only for a fixed time and access control devices of sites harmful to the teenager (such as pornography, violence, etc.) are required. Do. For this purpose, a computer control program requires a time management schedule database for using a computer and a database of an internet access site. Usage management allows you to set how many hours you use the computer a day, or enter a schedule that you can set for each day of the week or month. We also authorize unrestricted use of programs that are beneficial to adolescents (e.g., document writing, EBS educational broadcasting sites, edunet sites, etc.), and register additional databases in these beneficial programs and sites to spend more time using the computer. (OVER) You need to select an option to continue using the computer. In addition, access restriction of harmful sites for teenagers registers DOMAIN and IP in database and monitors relevant IP and DOMAIN in OS KERNEL's NETWORK protocol to prevent access to this site. And discard the packet data sent / received for the IP and DOMAIN. Therefore, it is possible to see nothing in the browser window, and in the case of EMAIL, the effect of blocking spam of unhealthy sites is simultaneously achieved. This is because it detects DOMAIN or IP of harmful site and discards relevant data in OS KERNEL and computer control program. The registration deletion and modification of the time management schedule database and the harmful site database must be processed by the computer control program so that the identification code from the portable radio transmitter can be compared with the radio receiver to be TRUE. In addition, for easy registration in the database of programs and sites, it is possible to receive automatic updates from the Internet server or to update users through the Internet network.

When installing the control program, the super master password is input and encrypted with a special code. This supermaster password is intended for temporary use of a computer when the portable radio transmitter is broken, lost or not brought. If the user fails to enter the password within a certain time after booting the computer when the portable radio transmitter does not function, OS KERNEL and the control program will not operate the user computer or shut down automatically. Therefore, the computer can be used only when the computer OS is newly installed. To protect this problem, make a special encryption code by combining the hard disk serial number, the network code of the network circuit, and the date (time), and then decrypt it using this encryption code and inform the user of the temporary password. I need to give.

9 is a countermeasure for the soft reset key

The apparatus of the present invention includes a portable wireless transmitter 2 of FIG. 1 attached to a computer, a wireless receiver 1 of FIG. 2, and a computer control program 3, which is to be used as a general computer system. Classified as (4), the portable wireless transmitter 2 designates the user's ID code, and the computer wireless receiver 1 also specifies the user's ID code. It also programs the computer control program device 3 to encrypt and store its ID code.

In FIG. 4, the portable wireless transmitter 2 transmits its ID code wirelessly at predetermined time intervals so that the user is close to the computer system 4 from the wireless receiver 1 in his computer system 4. Inform. Receives the ID code transmitted from the wireless transmitter 2 in the wireless receiver 1 and sends it to a computer control program. In this case, the computer control program 3 compares the encrypted ID code with its own, and if it is the same, the mouse and keyboard can be operated so that the computer system 4 can be used. If the portable radio transmitter 2 is out of a certain distance, the radio receiver 1 cannot receive the ID code of the portable radio transmitter 2. If this ID CODE is not received for a certain period of time, the computer control program 3 determines that the user is in a non-use position of the computer, and the lock device operates to prevent the computer control program 3 from automatically using the mouse and keyboard. Done. On the contrary, when the user accesses his or her computer system 4, the lock is released by the operation switch (a) of FIG. 1 of the portable radio transmitter 2, or the portable radio transmitter 2 periodically If you wait for that time as your ID code is sent, your computer system 4 is automatically unlocked.

In the case of FIG. 3, if the access is made to another person's portable radio transmitter 2-A, the ID code transmitted is different. Therefore, the ID code received by the radio receiver 1 is not recognized in the control program. It is supposed to be. In this case, if the ID code is not sent to the computer system 4 for a predetermined time, the locking device operates so that the keyboard and mouse of the computer are not operated. Therefore, the user can not access and operate the computer without the user's permission. However, if the user accesses the computer and is in operation, his / her ID code is received, so that the computer can be operated even if another person approaches. This is because the ID code is received by the receiver 1 because the portable wireless transmitter 2 continues to operate at a predetermined time period.

When the wireless receiving device 1 is removed from the computer system 4, the ID code cannot be received, so that the locking device is automatically operated so that the mouse and keyboard of the computer cannot be operated. However, if the computer control program 3 selects the self-locking device release mode (option) while the wireless receiver 1 is attached to the computer, the wireless transmitter 2 and the wireless receiver 1 do not exist. In addition, it is possible to release the locking device by making it in the computer control program 3 so that the mouse and keyboard operate.

When there are several radio transmitters 1 in the same space, the radio transmitter 2 is random inside the radio transmitter 2 in order to prevent ID codes from being simultaneously transmitted wirelessly at the same time. Time generation (random numbers) is used to avoid radio transmission collisions as much as possible.

1 shows a switch (a) and (b) in a portable radio transmitter 2. Switch (a) is the unlocking switch and switch (b) is the switch for operating the locking device. In some cases, individual codes are sent to be processed by the control program so that they can be operated by this operation switch.

5 shows that in order for the intruder to operate another computer, the wireless receiver 1-A is replaced with the wireless receiver 1-A having the ID code of the intruder and the portable wireless transmitter 2 -A of the intruder. When attempting to access the computer system 4 by using the present invention, the operating configuration of the present invention is first replaced by the intruder's wireless receiving device 1-A. Compare the encrypted ID code with the ID code of the intruder's wireless receiver (1-A). At this time, because the ID code is different, the locking device is activated to prevent access. At this time, the device 3 operates to generate a warning message or an alarm sound. Therefore, even if the intruder attempts to access the portable radio transmitter 2-A, it is meaningless.

The wireless receiving device, which is the device 1, receives an ID code and transmits the ID code to a computer control program through an input / output device of a computer. At this time, the input / output device of the computer can be applied to any one of the USB port, the PRINTER PORT, the SERIAL PORT, and the INTERFACE CARD, and the computer program is programmed to recognize the wireless receiving device.

The computer control program (3) device initially allows the operation of the mouse and keyboard if the content is encrypted after the ID code is encrypted and stored and compared with the function of comparing the ID code sent from the radio receiver 1. If the comparison is false, it disables the mouse and keyboard.

The computer control program 3 operates together when the OS of the computer starts to operate. When the ID code of the portable radio receiver 1 does not receive for a predetermined time, the computer control program 3 recognizes that the user has departed a certain distance. The computer control program (3) intercepts OS KERNEL messages for the mouse and keyboard in the computer control program (3), and then sends the mouse and keyboard messages to the KERNEL of the computer OS. Sending a message to KERNEL makes computer operation impossible.

If the ID code of the wireless receiver 1 received from the portable radio transmitter 2 is the same as its own ID code, it is possible to operate the computer by sending a message to the OS KERNEL to operate normally.

For the security of the computer, the ID CODE has a double configuration. First, the function of comparing the ID CODE between the wireless receiving apparatus 1 and the computer control program 3, and secondly, the transmitting apparatus 2 and the receiving apparatus. There is a function for comparing between devices of the device 1. If the first ID CODE is different, the computer system 4 will lock the mouse and keyboard inoperably. In the second case, the ID CODE will not be received for a certain time or the received ID CODE will remain within a certain time. If it is not the same as its ID code, the mouse and keyboard operation of the computer system 4 will be impossible. When its ID code is received while computer operation is impossible, the computer system 4 automatically unlocks the mouse and keyboard to enable operation.

Fig. 6 is a flowchart for managing a group, in which the portable radio transmitter and the receiver have respective identification codes (ID CODE), and in the control program, the computer license ID code can be registered. For example, if the system administrator inputs the system administrator's ID code to operate the entire computer, and the team leader's ID code is registered on the computer of the relevant team, the system administrator can access any computer. In addition, the relevant team leader can only access the computer of the team.

FIG. 7 is a flowchart illustrating a method for limiting computer use time and restricting access to a site, and a function for preventing use of the computer when it is used for a predetermined time or longer and a function for not time limiting for a beneficial program or site are required. In addition, sites that are not profitable need to be blocked. The operation method in the control program will be described. This feature is commonly used at home and requires an option to operate without a portable radio transmitter, except for setting up programs for database access and control. The control program has a function to select these functions, and it is possible to determine whether or not to use the identification code of the portable radio transmitter according to the option selection. And restricting matters related to site access. In case of restriction of obscene site, it monitors the data of computer network, and when the related sites (DOMAIN and IP) are confirmed, it sends a disconnect command signal to the other network system and discards all already received data or additional incoming network data. This operating method is determined by the setup program to allow various types of actions to be taken by the administrator.

8 is a super master password is required in case the super master password can not be transmitted due to the loss or failure of the portable radio transmitter. This function is executed at the same time when the control program (3) is booted on the computer, and if the portable radio transmitter does not function normally, the computer cannot operate the keyboard and mouse after booting. Also, if the identification code is not input for some time after booting, the computer will automatically shut down. Therefore, the user will be able to use the computer only after a new installation of the OS of the computer. In order to prevent such inconvenience, the user can use the serial number of the computer's hard disk, the machine number of the network circuit, the date (time), and the identification code to decrypt the data with the encrypted data according to various methods and selectively encrypt the user. Inform the user that they will be able to enter and use a temporary password for their computer. Within a certain period of time, no password is available except for the computer. For that reason, the encryption code varies according to the first time, and the second hard disk serial number and the network number of the machine circuit are rarely matched with other computers. Therefore, the temporary password only applies to that computer, and after a certain time the password becomes a useless password. Therefore, with a temporary password, the user may choose not to use the radio transmitter according to various choices in the setup program, and the computer will be temporarily available until the radio transmitter function is normalized. At this time, the super master password can be changed so that no password request is required again.

On the computer's operating system there is a soft reset key. For example, Microsoft's operating systems, such as Windows 95, 98, XP, and so on, will cause a soft reset by pressing CTRL + ALT + DEL on the keyboard. At this time, if the processor of the control program belonging to a part of the present invention is stopped, there is no meaning. In order to prevent the problem of Microsoft's OS, two methods are devised and selectable in the setup setting to be selectively used. First, when the soft reset key is input, the message of the soft reset key is transmitted to the OS KERNEL. . In order to invalidate this message, the soft reset key input data is hooked up and the message is requested to be discarded by KERNEL and the control program is operated in duplicate (executing the same two programs). In this case, only one processor can be stopped when performing a soft reset and stopping the associated processor. Therefore, if duality is skipped in the control program and one processor is stopped, a new processor (control program) is run again, and no processor interruption is caused by a soft reset. These functions allow for optional management in the control program's options. In the case of UNIX and LINUX OS, if the user logs in in the normal USER mode, the daemon cannot be stopped in ROOT mode so that the processor cannot be stopped. However, if you logged in as ROOT, you already logged in with the ROOT password, so the system must grant all the functions to ROOT, so there is no need to mention soft reset and processor interruption anymore. Therefore, the contents of this soft reset apply only to Microsoft OS.

In today's information age, computers are a necessity, and most are already using computers. Many people, including individuals and businesses, use computers, but important information about themselves or companies is contained in computers. In today's era, the Internet has evolved and most computers are connected to high-speed Internet network systems. But if the computer contains important information or trade secrets, then the information on the computer and its secrets will be high. If you have important information or trade secrets on your computer, you may not want to be exposed to visitors or others. If your computer is a condition that others can manipulate, you can send all or some of the data on your storage device to another person's E-mail or another person's storage system via a storage device or an internet line. Will expose the information. In order to prevent this, a locking device has been developed to automatically limit the operation of the keyboard and mouse, which are essential for computer operation, by the wireless transmission / reception device. When the user moves away from the computer, the locking device automatically operates to prevent the mouse and keyboard from operating. Even if you go out for a while, the computer will not be able to operate the computer automatically. You will be protected from sensitive information or trade secrets from others.

In addition, in the case of a home, children or adolescents are unable to access harmful sites (indecent, violent, etc.), and spend a lot of time using computers for general games or online games, chatting, and the like. Because of the lack of self-control of adolescents, it is expected that if the device of the present invention does not allow the user to use the computer for a limited time or access the harmful site of the adolescent, it will greatly help the adolescent's proper growth and mental health.

Claims (4)

It is a device that prevents you to operate the mouse and keyboard of the computer to make it impossible to operate the computer when you are not confident. When you are within a certain distance between the portable radio transmitter and the device of the wireless receiver, the identification code In this case, the wireless receiving device sends this identification code to the computer so that the mouse and keyboard can be manipulated so that the signal of the mouse and keyboard can be normally transmitted to the OS KERNEL by the computer control program. If the portable small power wireless transmitter and the wireless receiver are out of a certain distance, the opposite process, the ID code will not be received. Therefore, if the receiving device does not receive the identification code within a certain time, the computer control program sends a signal to invalidate this signal to OS KERNEL so that the computer's mouse and keyboard cannot be operated, and the intruder replaces the portable wireless receiver. When a computer control program reads the data, it sends a message to OS KERNEL so that it does not receive data signals from the computer's mouse and keyboard, and prevents the mouse and keyboard from being manipulated. Keyboard and mouse can be operated according to the ID code in the control program so that the user range can be varied. The ID code received from the transmitter / receiver can be used as USB PORT, SERIAL PORT and PRINTER PORT. To any computer in the INTERFACE CARD The number of control programs and devices to be treated so. In order to block or allow access to the computer usage time and access to sites (DOMAIN, IP), the control program uses a database to receive computer usage time or schedule on a daily, weekly, or monthly basis in case of usage time restrictions, and sites that allow or deny access. In order to manage the program as a database, the computer control program compares the ID code sent from the portable radio transmitter with the identification code of the radio receiver and if it is TURE, the device for processing the related database to be modified and deleted. In the case of time limit and time limit, the function of the computer will be restricted or automatically shut down when the available time is used up, and in case of a licensed program or site, the function and the unauthorized site will be allowed to operate the computer regardless of the time. Display and do a message The remote system update to enable the function and use of the site permission and non-permission data and programs to dispose of the data from a network of sites in the OS KERNEL and control program between the Internet server or personal computer. In case a portable wireless transmitter containing a user identification code fails to function due to loss or malfunction, it is stored in a special encrypted form when a super master password is input when the computer control program is installed. If the portable wireless transmitter does not function, the user's computer will run with a control program at boot time, so if the super master password input is not successful within a certain time, nothing will be allowed to operate (mouse and keyboard). Therefore, the manufacturer can create a special encryption code by combining the ID code with the computer's hard disk serial number, the unique machine number of the network (Ethernet) circuit, and the computer's date (time). System that informs the user of a temporary password after decrypting the data. On the computer's operating system there is a soft reset key. As a way to prevent the soft reset function, Microsoft's OS (WINDOWS 95, 98, XP, etc.) will cause a soft reset by pressing CTRL + ALT + DEL on the keyboard. At this time, the processor for hacking prevention or system monitoring is running among the running processors, but if the processor is stopped by using the function of soft reset and a third party accesses the computer, the computer is not protected. In particular, if a soft reset key is entered to prevent problems with the Microsoft OS, the soft reset key message is sent to the OS KERNEL. In order to invalidate this forwarded message, you can hook the soft reset key input message data and request that this message be discarded at KERNEL, and the program running at the same time as the running processor monitoring program. If you register in the database and note that Microsoft's OS stops the processor by soft reset, only one processor can be stopped. Using this property, the ability to automatically create (execute) a new processor (processor monitoring program) from another processor monitoring program even if one monitoring program is interrupted, and if the processor registered in the database stops Automatically execute this program when the processor of the program registered in the database is interrupted, including the ability to automatically run the related program in the monitoring program.
